Heat a manchatti and add the coconut oil. Crush small onions, garlic and ginger using a mortar and pestle. Add the crushed mixture to the heated oil and saute for couple of minutes. Throw in a sprig of curry leaves. Now add the ground coconut mixture into it. Stir well. Once it starts to boil, add the sliced raw mango pieces and the cleaned sardines. Cover and cook. Open the lid in between and gently stir. Check for salt and add as required. Once the sardines are cooked well, switch off the stove. If the curry isn't tangy enough, add some vinegar towards the end.

In a non-stick pan, heat 1 tbsp of coconut oil and add sliced small onions and curry leaves. Once they turn brown and crisp enough pour it into the sardine curry and keep the chatti closed for sometime, to allow the flavours to set in. Your yummy sardine curry is ready!! It tastes wonderful with boiled rice as well as puttu.
